Fuel Economy Overview

The 2006 Hummer H3 4WD achieves an EPA-estimated 16 MPG in combined city and highway driving, with 14 MPG in the city and 18 MPG on the highway. Powered by a 3.5L 5-cylinder engine paired with a manual 5-spd, this sport utility vehicle - 4wd features 4-Wheel or All-Wheel Drive drive.

In terms of environmental impact, the 2006 H3 4WD produces approximately 555 grams of CO2 per mile. This figure is measured under standardized EPA test conditions and represents tailpipe emissions only. For context, the average new vehicle sold in the United States produces approximately 400 grams of CO2 per mile, meaning this H3 4WD has higher-than-average emissions in this regard.

The estimated annual fuel cost for this vehicle is $3,750, based on 15,000 miles of driving per year and current national average fuel prices. Compared to the average new vehicle, you would save $8,000 over a 5-year period. This calculation accounts for differences in fuel consumption efficiency and provides a practical measure of long-term ownership costs attributable to fuel economy.

The Brick Effect: Highway Speed Penalty

EPA highway tests average roughly 48 mph. Driving at 75 mph increases aerodynamic drag exponentially. Because the Sport Utility Vehicle - 4WD has a large frontal area, expect your real-world highway fuel economy to drop by up to 25% at high speeds.

Component: STRUCTURE:BODY:HOOD

GM IS RECALLING CERTAIN MODEL YEAR 2006 THROUGH 2010 HUMMER H3 VEHICLES. SOME OF THESE VEHICLES HAVE A CONDITION IN WHICH THE INTEGRAL CLIP-TABS ON THE LOUVER ON THE HOOD MAY FRACTURE, CAUSING THE HOOD LOUVER RATTLE AGAINST THE HOOD AND BECOME LOOSE. IF THIS INDICATOR IS UNNOTICED, ADDITIONAL CLIPS COULD FRACTURE AND THE HOOD LOUVER COULD DETACH FROM THE VEHICLE.

Consequence & Remedy

Consequence: IF THE VEHICLE IS BEING DRIVING WHEN THIS OCCURS, IT COULD STRIKE A FOLLOWING VEHICLE AND CAUSE INJURY AND/OR PROPERTY DAMAGE.

Remedy: DEALERS WILL APPLY AN ADHESIVE TO THE HOOD LOUVER TO SECURE IT TO THE HOOD. THIS SERVICE WILL BE PERFORMED FREE OF CHARGE. THE SAFETY RECALL BEGAN ON APRIL 12, 2010. OWNERS MAY CONTACT HUMMER AT 800-732-5493 OR AT THE OWNER CENTER AT WWW.GMOWNERCENTER.COM.

Campaign #06V417000·2006-11-06
critical
Component: AIR BAGS:FRONTAL

CERTAIN VEHICLES ORIGINALLY BUILT WITH CLOTH SEATS THAT WERE EQUIPPED WITH AN AUTOMATIC AIR BAG PASSENGER SENSING SYSTEM AND LATER REUPHOLSTERED WITH AFTERMARKET LEATHER SEAT COVER KITS ARE INVOLVED. TESTING HAS INDICATED THAT THE AFTERMARKET LEATHER SEAT COVERS CAN CAUSE THE PASSENGER SENSING SYSTEM TO MALFUNCTION.

Consequence & Remedy

Consequence: IF THE PASSENGER SENSING SYSTEM MALFUNCTIONS, THE FRONT AIR BAG ON THE PASSENGER SIDE MAY BE DISABLED WHEN IT SHOULD BE ENABLED, OR ENABLED WHEN IT SHOULD BE DISABLED. IN EITHER CASE, IN THE EVENT OF A CRASH THAT REQUIRES AIR BAG DEPLOYMENT, A FRONT PASSENGER'S LEVEL OF INJURY MAY BE INCREASED.

Remedy: BECAUSE A REPLACEMENT LEATHER SEAT COVER THAT IS COMPATIBLE WITH THE PASSENGER SENSING SYSTEM IS NOT AVAILABLE, GENERAL MOTORS (GM) WILL REPURCHASE THESE VEHICLES IN ACCORDANCE WITH THE TERMS STATED IN GM'S LETTER TO OWNERS. THE RECALL BEGAN ON NOVEMBER 6, 2006. OWNERS SHOULD CONTACT GM AT 1-877-477-1022 TO BEGIN THE PROCESS OF REPURCHASING THEIR VEHICLE.
